Every job gets a non-NULL job->txn on creation, but it doesn't
|
|
|
357786 |
necessarily keep it until it is decommissioned: Finalising a job removes
|
|
|
357786 |
it from its transaction. Therefore, calling 'blockdev-job-finalize' a
|
|
|
357786 |
second time on an already concluded job causes an assertion failure.
|
|
|
357786 |
|
|
|
357786 |
Remove job->txn from the assertion in block_job_finalize() to fix this.
|
|
|
357786 |
block_job_do_finalize() still has the same assertion, but if a job is
|
|
|
357786 |
already removed from its transaction, block_job_apply_verb() will
|
|
|
357786 |
already error out before we run into that assertion.
